About This Game

You are a commander tasked with defending Medieval Europe against a fearsome Alien Invasion, which historians agree definitely happened. Gesture vigorously to your elite, knight forces to command them into battle. You are the only commander brave enough to save the world by dragging tiny armies between towers with the urgency of someone who has just spilled coffee on a battle plan. Fail, and Earth may experience a brief administrative change in ownership.

Bears eat the world

DON'T LET THE WORLD GET EATEN

Knights vs Aliens is a free classic re-release of a small strategy game originally shipped to iPad in 2009 under Prophetic Sky. This version has been rebuilt in Godot for Steam, desktop, and web, then returned to public life because it is still weird and still fun.

CAUTION:

This intense historical experience may cause your FINGER to BREAK OFF and/or MELT. You may want to consult your NEXT OF KIN before use.

REQUIREMENTS:

KvA was designed to work with items found in your home. We don't actually know where you live, but I assume your computer will play it - if your computer can't compete with a 2009 era iPad, you should probably upgrade.

AI was used for graphics not included in the original 2009 release, such as achievement icons and store page banners.
